Chapter 6 Applied Instructions Example When M0 is ON, the FRAD instruction converts the floating-point number in (D11, D10) into radians, and stores the conversion result in (D21, D20). The FTAN instruction finds the tangent of the radian value in (D21, D20) and stores it in (D31, D30). The tangent value is a floating-point number.

If the value in S exceeds the range of values that can be represented by floating-point numbers, the instruction is not executed, SM0 is ON, and the error code in SR0 is 16#2013. 2.
If SM695 is ON, and the value in S is not between 0–360, the instruction is not executed, SM0 is ON, and the error code is 16#2003. 6-447
